Application filed November l, 1918. Serial No. 128,865.

To all whom t may concern:

Be it known that we, EDWARD C. HUM- rrriznrs and CHARLES E. ARCHER, citizens of the United States of America, residing at Detroit, in the county of `Wayne and State of Michigan, have invented certain new and useful Improvements in Traino-Signals, of which the following is a specification, reiference being had therein to the accompanying drawings.

rlhis invention relates to signals 'for auto mobiles and other vehicles and has special reference to a semaphore signal adapted 'for attachment tothe frame of a windshield or other parts of an automobile or vehicle convenient to the chauiieur.

The primary object of our invention is to combine a semaphore signal and reflector and attach the same to a windshield frame Ylor other support in a manner that permits of ready adjustment of the reflector so that the same may be conveniently used by a Chauffeur in making desired observations relative to tratiic in the rear or to one side of the reector carrying automobile.

V.another object of this invention is to provide an automatically actuated semaphore signal with means of illumination automatically controlled, and provision isy made for easily and quickly restoring the semaphore to normal or inactive position after having been automatically actuated.-

A. further objectof our 'invention is to provide an automobile signal'wherein the parts are constructed with, a view'to reducing the cost of manufacture and at the same time retain the `features by' which compactfness, durability, and ease of assemblingthe parts are secured. 'With such ends 1n View', our invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawings, whereina I Figure 1 is a front. elevation of the signal, partly broken away and partly 1n section, showing the semaphore arm 1n a retracted or inactive position;

Fig. 2 is a plan of the same, partly brolren away and partly in section;

Fig. 8 is a vertical sectional view of the signal casing showing the semaphore arm in an extended or active position; and

Fig. 4 is across sectional view of a inan-l ually actuated device forming part of the signal.

In the drawings, l denotes a portion of a windshield having a frame 2 and this windshield frame is simply illustrated as an eX- ample of a support in connection with an automobile for our improved signal. Attached to the windshield frame 2 and capable of lateral or horizontal adjustment about the vertical axis of the frame 2, is a clamp member comprising clamping portions 3 and bracket clamping portions 4. The clamp member, as a matter of good construction, is preferably made of four pieces with Ythe clamping portions 3 and 4 cylin drical and connected by webs 5 and 6, said webs adding rigidity to the frame clamping portions and the bracket clamping portions d, so that the frame clamping portions 3 are firmly held at aright ancle to bracket clamping portions 4. The webs 6 are connected by screw bolts and nuts, generally designated 7, constituting means for firmly clamping the frame clamping portions 3 on the windshield :frame 2, and the webs 5 are connected by similar means 8 which permit of the Clamping portions l of the member firmly holding a bracket arm t. This arm is tubular or a solid rodvcored out, and through the medium of the frame clamping portions 3, said bracket rod may be positioned at a desired angle relative to the windshield. i

Mounted on the bracket rod 9 is an adjustable clamping member 10 held by screw bolts and nuts7 generally designated 11. rEhe lower portionrof this adjustable bracket member supports a hollow casing` arm 12, practically rectangular in cross section, and by adjusting the clamping` member 10 upon the bracket rod 9, the casing` arm 12 may be shifted in a vertical plane. The inner end of the casing arm 12 has a slot 13 and depending lugs or hangers 14. Between the lugs 14 is pivotally mounted a sector shaped retracting member 15 having a handle 16 by which said member mayv be easily moved. rhe retracting member 1'5 extends through the slot 13 of the casing arm l2 into said casing and is provided With a groove 1? to receive a cable 18, said cable having the inner end thereof connected to the member 15, as at 19.' The retracting member 15 is' also provided with a transverse opening 20,

and adapted to extend in said opening is a pletes a circuit which will light the lamp 41. In order that the signal' may be used during the day without the semaphore arm being illuminated, an ordinary switch will be installed in the circuit and such switch, as well as other similar electrical devices that may he used, do not form any part of our invention.

We attach considerable importance to the fact that we utilize ay reflector support as a housing for a semaphore arm and that by having the semaphore arm spring actuated, it is possible to more quickly operate the signal, for instance in an emergency, than what it would be to swing a semaphore arm by hand. As it is, a jerk on the chain or cable accomplishes the desired result, and the semaphore arm may be reset at leisure. It

is also possible to wigwagthe semaphore' for attachment to an automobile or other vehicle and capable of adjustment in planes at right angles to cach other, a cylindrical casing carried by the outer end of said hollow arm and having the cylindrical Wall thereof provided with a slot, a rotatable spool in said casing adjacent the cylindrical wall and at one end of the slot thereof, a circular semaphore arm ycarried by said spool and adapted to be swung out of the slot of said casing, a spring actuated cable in said casing attached to said spool and normally in condition for swinging said semaphore arm out of said casing, a cable extending through said hollow arm into said easing and attached to said spool for restoring said semaphore arm to normal position within said casing, and a retreating member pivoted at the inner end 0f said arm and connected to said cable for controlling the operation of the semaphore arm. actuating cable.

In testimony whereof we aiiiX our signatures in presence of two Witnesses.
